Shows DX material with textures blended by vertex color in viewport. Has interface that allows user to switch between Standard and DX versions and also toggle display of ARGB channels.

Expects single selected object with Standard material or multiSubObject stuffed with Standards. Interface will indicate what option are available with current selection.
Will auto-fill DX material assuming that Diffuse is black, Specular Color is red, Specular Level is green and Glossiiness is blue channel. Will try to use previously existing materials for both DX and Standard modes or create new material if no old one is found.
You can also pick it from object and assign textures manually in material editor.
If selected object has multisub material applied you have to use spinner to indicate submat you wish to show as vertexColor blenbded.
NOTE:
With Scanline renderer material will be available in Materials>General> menu.
You can assign this material manually from Listener:
$.mat = dwvcdxmat()
For some reason max doesn't always register it properly and you would have to close interface and drag'n'drop .mse file 1 more time. Or 2 if it gives you an error. Sorry about that, doesn't happen when using interface and I don't know what's causing it atm
HOW TO USE:
Just drag-n-drop .mse file to viewport. Select an object with compatible material and press an eye icon.
